To all whom it may concern.'

Be it known thatfI, EDWARD HoEnIcHs, `a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented new and useful Improvements 1n Flushing Apparatus for l'Water-( )losets of which the following is a specification. 0

This invention relates to improvements 1n flushing apparatus for water-closets, and proposes a construction of the frost-proof type, the chief characteristics of which are that the flush tank and the waterV supply and discharge pipes are normally empty; the admission of water to said tank is controlled by a normally closed mainl valve which 1s suitably located under ground below the frost line; and the said main valve is .employed in combination with an` auxiliary valve which is normally open but 1s automatically closed during the periodin which the main valve is open and isy used to control the water flowing past the main valve, causing said water to pass into the flush tank so long as the vmain valve is open and thereafter and when the main valve iS closed permitting it to passthrough the flush pipe.

The object ofv the invention is to provide a construction of the type described having an improvement in the organization of its parts whereby all of the operating elements, including the main valve and its seat, are removable and. replaceableas a unit with respect to the pipe in which they are arranged, by virtue of which characteristic theV parts are quickly and readily accessiblefor the purposes of renewal, substitution or re-v pairs; having other improvements in the organization and construction of certain parts whereby the opening of the main valve will invariably be accompanied by a short preliminary and substantially immediate flushing of the closet bowl, and whereby this short preliminary flush is automatically terminated for an indeterminate interval prior to the main flush which takes place consequent to the opening of the auxiliary valve above referred to; having other features connected with the construction of the operating means whereby the valves are positively operated in either direction of movement and the auxiliary valve is positively held in closed relation; having certain further' features of organization which provide for simplicity of mechanical structure and reliability and facility of operation; V,and

having a further improvement in the provision offmeans for cushioning shocks conseseats,

quent to the sudden and forcible closure of the main valve. e

Other objects and advantages will appear as'fthe` description proceeds.

An embodiment of theinvention isillus;

trated in thev wherein y Y Figure l is a side elevation illustratinga practical application of the invention'where' in the opening and closing operations of the accompanying drawings,

niain'and auxiliary valves vare initiated `and* automatically controlled by the closet seat, which seat has a normally elevated position wherein' it is substantially perpendicular; Figs. 2 and 3 are vertical longitudinal sectional views, Fig. 2 showing the main and auxiliary valves and the closet seat in their normal positions, and Fig. 3 showing the closet seat depressed, the auxiliary valve closed and the main valve open; Fig. 4 is a horizontal sectional View in the plane oftlie rock shaft which controls the operation ofV the valves; Fig. 5 is a fragmentary vertical cross-sectional view in a iplane at right angles to Figs. 2 and 3 with the parts related as in Fig.3; Fig 6 is a detail horizontal sectionaly view on the lineG-,G of Fig. 2; Fig. 7 is a detail perspective view of a washer which is employed in the organization of the seat-operated rock shaft; and Fig.v 8 is a detail perspective view of a cross head which adjoins the augiliar'y valve and forms an element of the operating means.

kSimilar characters of reference designate corresponding parts throughout the several l views. l y y Y The closet bowl l is of any suitable construction and is equipped with a seat 2 which normally occupiesa substantially vertical position. The lwater which flushes the bowl is stored in a normally empty tank 3 having a pipe 4 through which water both.

enters and discharges from said tank. The bowl l is equipped with a flush pipe 5 and the pipes 4 and 5 are connected to a normally empty supply pipe 7 which projects for some distance into the ground and at its lower end is joined to a water-main. Y

'ghe pipe 5 is arranged above the pipe 4; an

lower end thereof and'y is engaged by a main valve 9V and the` other of which l() is, arranged between the points of connection of thepipes 4 and 5 with the pipe 7 and is engaged by an Iauxiliary valve 1 1. The valves the pipe 7 is provided with two valver one of which 8 .is arranged near thev 9 and ll are mounted upon a connnon valve,

stern 12, the valve 9 being disposed belovv7 its seat 8 and the valve 1l beingv disposed above its seat 10. By virtue of these features of relation, when the main valve 9 is closed the auxiliary valve 11 is opened, and when the main valve 9 is opened the auxiliary valve 11 is closed. It follows fronrthis that the water which flows into the supply-pipe 7 when the main valve is opened cannot pass directly to the bowl, since the auxiliary valve is closed and, therefore, must pass through the pipe 4 into the tank L-wherein it accumulates against the pressure of air in the upper portion of said tank. When the relation of the valves is i-eveised, that is to say, when the main valve is closed and the auxiliary valve is opened, the water stored in the tank 3 in the manner just described flows downwardly through the pipe ai and enters trie supply pipe 7 from which it passes through the pipe 5 to the bowl, flushing the latter. The water which backs up in the supply pipe 7 in connection with the operation of' the iushing apparatus escapes through a drain port 13 controlled by the drain valve 11i. The drain valve 14 is supported in the closed position of the main valve 9 in spaced relation above the drainage opening 13. However, when the main valve 9 is opened the valve 14 becomes operative to close the drainage opening 13. The valves 9 and 11 are of course correlated by the stem 12 which is common to both of them and their operation is positively effected and controlled by the seat 1 which has as its pivotal axis a rock shaft 15 and in its movements turns said rock shaft and through certain intermediate connections operates the valves.

The above features, broadly considered, are well known in the art and the present invention proposes certain specific improvements which are grafted, so to speak, upon the features of construction and organization above explained and which will be clearly brought out as the description proceeds.

The operating means for the valves includes as an essential element the rock shaft 15 above referred to, which rock shaft has its ends journaled in an extension 1G of the pipe 7 arranged above the pipe 5. The said rock shaft carries a V-shaped cam 17 which works in a vertical slot 18 of a cross head 19 and is provided with co-extensive engaging arms 17'd and 17. The cross head 19 forms, in effect, a continuation of the valve stemv 12, and in the embodiment shown is integral with the auxiliary valve 11. Said cross head has its side bars provided with alining slots 19 through which the shaft 15 projects and which'permit said cross head to move vertically and relativelyto the shaft 15. The slot 18 alineswith a recess 2Ov at onelside of the extension 16 and the arms ofthe cam 17 project into the recess 2O in the course of their movement. The cam 17, by the engagement of its arms 17*l and 17 with the respective upper and lower portions of the cross head 19, is effective to positively raise or lower said cross head and therewith the connected auxiliary and main valves. rEhe cam 17 is of course fast on the rock shaft 15 and its operative movements are due to the turning of said rock shaft, which, in turn, is effected by movements of the seat 2.

The seat 2 is provided, as usual, with a hinge casting having parallelrearwardlydirected arms 21 and 22. rlfhe arm 21 carries a trunnion 28 which engages in a bearing 211 provided at one side of the extension 16 and the arm 22 surrounds the shaft 15 which at one end projects beyond the extension 16. rThe shaft 15 is journaled in a bearing 25 internal to the extension 16 and in a stuffing box 26 at the side of the said extension opposite to said bearing and it is held against endwise displacement by a U- shaped washer 27, (Fig. 7), which is fitted in an annular groove 28 in the shaft 15 and is arranged within the cap of the stufling box 2G. rlfhe means for holding the seat 2 in a normally elevated position preferably comprises a counter-weight mounted on an arm 22 and the stalling box 26. The influence of this counter-balance weight is transmitted to the seat by a bracket 8O having an arm 31 which engages under the arm 29 and an arm 32 which engages under tae arm 22. The bracket 30 is fast on the shaft 15 and, therefore, turns said shaft in accordance with the movements of the seat 2. The object in using the bracket 30 as a means of connection between the counter-weight and the shaft 15 is to enable an adjustment of the position of said counter-weight whereby its leverage may be increased or decreased as desired, and such adjustment is effected by a screw 33 carried by the arm 31.

' rlhose portions of the shaft 15 upon which the disk 17 and the bracket 30 are mounted are preferably square or flat sided in cross section and said disk and said bracket have openings for the shaft which conform to its fiat sided cross section. The bracket is held in place b v a washer 341 which is secured to the shaft 15 by a screw threaded into the outer end face of said shaft. The seat 10 for the auxiliary valve 11 has its opening of greater diameter than the external diameter of the seat 8 for the main valve 9. The said seat S is threaded in the lower portion of the pipe 7, or, more strictly, in a reduced extension 3G of said pipe and, being arranged above the valve 9 as previously setV forth, may be removed from the pipe 7 with said valve. In removing or replacing the valve seat 8 it is of course necessary to engage or disengage it with respect to the a 13eme y Vmating threads in the extension 36, and for this purpose the opening 37 in the valve seat- 8 through which the stem 12 passes is somewhat oval or elongated and that portion of the valve stem which Y normally fits said opening has an elongated cross section, as

. been disengaged from the threads in the extension 36 the operating parts of the device may be removed as a unit from the pipe 7, although in order that such disengagement of said valve seat may be effected, it is of course obvious that'the shaft 15 must have beenpreviously withdrawn from its bearings in the extension 16. Those operating parts which are removable as `a unit are the cross head 19, the auxiliary valve l1, the main valve 9, the stem l2 which connects and correlates said auxiliary valve and main valve, the main valve seat 8 which is supported on the main valve during its removal,rand the drain valve 14.

The drain valve 14 is normally supported in spaced relation above the drain opening 13 by a flange 38 which circumscribes the stem 12 near its lower end. Almostimmediately, however, following the initiation of the downward movement of the main valve the valve 14 comes to rest over and closes the drainopening 13. The said valve 14 is preferably in the form of a disk which somewhat loosely surrounds the lower portion of the valve stem 12 and in its lower position, in which it closes the drain opening 13, it rests'uniformly upon a shoulder 39 provided at the upper end of the extension 36. In view of the structural character of the drain valve and'its relation to the main valve, it is necessary for the water which flows Vpast the main valve to have aby-pass circulation with reference lto the drain valve in order that itmay not effect the unseating thereof. For this purpose, the stem 12 is preferably made in sections and its lower section, which carries the main valve, is formed with a water duct 40 com municating at its lower end with a water inlet opening 41 and at its upper e'nd with a water outlet opening 42. The opening 41 is arranged slightly above the main valve and almost immediately that the main valve leaves its seat 8, water passes through the opening 41 into'the duct 40 and issues from the latter into the pipe 7, the water thus entering the pipe 7 aiding, by its weight or head, in keeping the drain valve closed.

The invention also proposes certain features vof construction whereby immediately that the seat isvdepresseias shown inf-Figffl,

a short vpreliminary flush will take plac: In order thatthis result may be positively insured, the upper member of the stem 12 is provided with a water duct 43 which at its lower end communicates withl the water in-' let openings 44 and at its upper end communioates with water discharge openings 45. The openings 44 are controlled by suitable flap valves 46 which tend to spring outwardly. By virtue of these features of construction a percentage of the water which Hows into the pipe 7 will pass through the normally uncovered openings 44 into the duct 43 from whence it discharges through the openings 45'into theflush pipe 5, and this result takes place eveny though the auxiliary valve 11 be closed, At this point, it may be'noted that there ,will be an interval in the operation ofthe apparatus when the auxiliary valve 11 and the main valve 9 will be simultaneously open and that the preliminary Hush desired would doubtless take place by virtue of this interval of n simultaneous opening in the event that-the seat 2 were lowered sufficiently slowly to enablerthe `water to reach the fiushpipe `5 before the auxiliary valve 11 became seated. However, if this period of simultaneous opening of the auxiliary and main valves were aloneY relied upon to provide `the preliminary flush, such Hush would be defeated in those cases where the seat 2 was lowered with suiiicientrapidity to insure the closing of the auxiliary valve'before the waterin the pipe 7 reached the elevation of the pipe 5, but by virtue of the provisionof the duct 43 in the valve stem 12 the preliminary flush desired is not affected by or in any way dependent upon the speed with which the seat 2 may be lowered since said flush will take place when the auxiliary valve is closed. As above pointed out, the flap valves 46 tend to spring outwardly and to uncover the openings 44 so that when vwater first enters the pipe 7 it is free to pass through the duct 43 into the flush pipe 5. 'In the meantime, water is of course rising in the pipe 7 and in the pipe 4, ultimately passing into the tank 6, andv when the head of the water thus rising through the pipes 7 and 4 and into thetank 6 has accumulated su-flicient force to'close the valves 46 against their tendency to spring outward and against the internal pressure of the water in the duct 43, the preliminary Hush is arrested.` yThe next flush that takes place is of course the main flush and the interval between the preliminary ilush and the main Hush corresponds to the intervalfin which the seat 2 is depressed.

Owing to the short and rapid movement o'f the main valve 9 to closed position there lisa liability, especially where Atherservice pressure is heavy, of the development ofv an thus providing an internal air chanibei' l1-9 in surrounding relation to the pipe 4l' and in which there is an accumulation of air which effectively cushions the shoclr incident to the closing of the main valve. rIhe casing 43 is formed with a mouth 50 which alines with the mouth of the pipe el? and which is suitably threaded for. connection to the coupling member which establishes communication between pipe 117 and the water main. l

To facilitate the removalrof the unitary valve structure, the cross head 19 is provided at its upper' side with a square plug 51 which works in a socket 52 of the cap 53 that closes the upper end of the extension 16. The plug 51 has such length that it projects beyond the upper edge of the extension 16, even in the lowest position of the cross head 19. 1n this way said plug is always accessible for engagement by a Wrench or other` suitable implement.

1n order to remove the unitary valve structure the cap 53 is first removed from the extension 16. Then the cam 19 is turned until its two arms are symmetrically related to the central longitudinal axis of the cross head at which time said cam is wholly out of the recess 20, and the plug 51 is wholly beyond the extension 16 whereby said plug is accessible for engagement by a wrench throughout its length. The shaft 15 is then removed and the unitary valve structure is held in an elevated position and at the same time rotated by the wrench or other implement used. rThis rotation causes the disengagement of the valve seat 8 from the threads of the extension 36 at which time the whole internal organization may be removed as a unit from the pipe i'. 1n case the valve structure should be dropped during the operation of effecting its removal, its downward movement will be arrested by the engagement of the auxiliary valve upon its seat 10 but in such position the plug 51 will project to some extent beyond the upper edge of the pipe 17 wherefore the removal of the valve structure may be readily resumed.

The cross head 19 preferably has at its upper side suitably arranged recesses 54 provided for the purpose of enabling an inspection of the cam 17 in connection with the removal of the valve structure in order to determine, in case the valve structure should accidentally be dropped ,while being removed, whether the cam 17 has been jarred from position so that it projects into the recess Q0. 1f such should be the case the cam must be disengaged from the recess 20 before the operation of removing the unitary valve structure can be resumed. rThe displacement of the cam 17 from the cause stated is not liable to occur however since the ends of its arms are somewhat tiattened at an angle, in order that they may present 'Hat bearing surfaces to engage the cross head 19 when the cam is turned, as above explained, to bring its arms in symmetrical relation to the central longitudinal axis of the cross head.

rl`he form lof cam 17 herein shown is preferred in that it is readily disengageahle from the recess 20 in connection with the removal of the suspended valve structure and effects the positive lowering as well as the positive raising of the valve structure. 1n this way, the auxiliary valve is positively and forcibly held in closed relation and mere gravity is not relied on. Consequently, the accidental upward displacement of the hammering of said valve due to an excess pressure of water which might be liable were the seating of the valve impositive, is absolutely prevented.

rlfhe operation will be readily apparent from the foregoing description. When the seat 2 is in an elevated position, as shown in Fig. 2, the main valve 9 is closed, the drain valve is open. and the auxiliary 'alve is open. This relation of parts obtains during and subsequent to the main iiush. Any water which may have columned in the pipe 7 incident to the discharge of water from the tank 3 escapes through the drain port 13. 1n this way the pipes 7 and i and the tank 3 are normally empty. Vhen the seat is depressed the auxiliary valve 11 is lowered upon its seat l0 and the main valve 9 is opened, and thedrain valve 14 closes the drain port 13. lVhen this relation obtains water tiows into the pipe 7 in the manner explained, the water thusl entering the pipe 7 flowing in part through the bypass duct 43 to the flush pipe 5 and producing a preliminary flushing of the bowl and in greater part through the pipes 7 and 4 into the tank 3. Vhen the head of the water in the pipes 7 and -t becomes sufficient to effect the closure of the valves 4G the preliminary flush is arrested. Subsequently, the seat 2 is restored 1 to its normal elevated position, the main valve is closed and the auxiliary and drain valves are open. Thereupon, the main Hush takes place and the excess water escapes through the drainage opening 13, as above explained.
